For decades, the Acoustic Doppler Velocimeter (ADV) has been the preferred instrument for precisely-defined sampling of water velocity across a wide range of environments. The FlowTracker2 ADV utilizes SonTek’s continuing innovation in ADV platforms to offer a laboratory version of the world’s best-selling ADV, the FlowTracker2. For the first time, the ADV’s acoustic probe and processing electronics are housed in one small, lightweight, easily maneuverable unit, and the acoustic head has an optional, integrated pressure (depth) sensor.

Depth data are even correctable for dynamic pressure (Bernoulli) and altitude effects using SonTek’s patent-pending method. Setup of the probe and PC software is simple and mistake-proof. Just connect the cables between the probe and your laboratory PC or laptop, check a few settings, and press the “Start Logging” button. Data are output directly to a .CSV file that is immediately ready for use in the project, model, or database as required.

In three simple steps, the FlowTracker2 ADV delivers robust, high-quality data right out of the box. The software interface writes data directly to a *.CSV file which can then be further processed, analyzed, or imported into other programs according to your project needs.

Questions & Answers
What is the purpose of the optional depth sensor?
During a discharge measurement, a typical user will read the water depth from wading rod markings. With a the integrated depth sensor, water depth can be measured automatically, reducing human error in the field and providing increased accuracy.

PME miniDOT Logger: Plunge into Data

The PME miniDOT Logger is a compact data logger that measures dissolved oxygen (DO) and temperature down to 100 meters in depth. The unit can also endure low water temperatures and is durable underneath an ice layer, which is excellent for gathering essential winter water quality data that is lacking from using less robust equipment. The high depth rating and ability to withstand frigid temperatures make the PME a reliable device that is deployable in dramatically different environments, such as a monitoring well, an inland lake or an underwater cave. The logger itself features an optical DO sensor, temperature sensor, two AA lithium batteries and a micro SD memory card.

The Water of Life: How Understanding Natural Hydrologic Processes in Aquatic Ecosystems Can Lead to a Sustainable Future

From watersheds that provide drinking water, the rain that nourishes plants, to the streams and rivers that help aquatic ecosystems flourish, water is an ever-present and ever-essential part of life. For those like Durelle Scott, a professor of Biological Systems Engineering at Virginia Tech University, understanding the importance of these natural systems was always a part of life. The desire to preserve the nation's aquatic resources stems from a childhood spent exploring the lakes and streams that surrounded him growing up in rural Pennsylvania. Now, as a teacher and a researcher, Scott makes it a priority to ensure that people now and in the future appreciate the enormous impact that aquatic ecosystems have on their lives. “I would say that water connects us all.

Lufft WS800: Introducing A Station that Can Weather the Storm

The Lufft WS800 Multi-Parameter Weather Station measures a full suite of atmospheric parameters that provides all-encompassing data on the local environment, including a one-of-a-kind lightning detector. This compact, cost-effective sensor simultaneously measures air temperature, humidity, pressure, precipitation, solar radiation, lightning, and wind with an integrated electronic compass. An internal fan and heater reduce the effects of external influences for accurate measurements during long-term deployments. The sensor can be easily mounted on a 2-inch diameter pipe above any local obstructions with the included bracket mount, U-bolts, and 10-meter cable.  Settings for the unit can be adjusted using the latest UMB-ConfigTool.
